When logging out, notice the other options presented. Ubuntu allows for you to switch to another user without
having to log out. This is especially handy when you are sharing a computer. The most important option on the
logout display is the Lock Screen option. Locking the screen when you are away from your computer is a good line
of defense against hacking. Most hacking in corporations happens within the confines of the company itself, rather
than a person or persons on the Internet. Good computer security starts right at your desk. Whenever you are not
at your computer, lock the screen. Then you will not have to worry about others looking at, editing, or — worse
yet — accidentally deleting your files.
Another useful option is hibernation. This choice puts the computer to sleep without shutting it down completely. If
you have never used hibernation before, consider it because it is a great way to be able to shut down your machine
and conserve either AC line power or battery power without losing your place within your work. When a machine is
hibernated, it is completely shut off, drawing no power.
